The visuals don't change too much in this film, but that's just a minor thing, and doesn't really impact on it at all - it's the story and the script that really got me hooked!
Yes, another film about time travel, without the CGI & SFX seen elsewhere.
The performance by the two main actors was very convincing, and the dialogue very thought provoking. The other two actors weren't as impressive with their delivery from time to time (haha), but don't let that put your off.
I had goosebumps several times in this film and enjoyed just about every minute of it.
What tipped me over from 6 to 7/10 was the ending, it almost seemed to end... naturally.
I very much liked this film!
